I Application filed January 21, 1904. Serial No. 190,038. v

To ctZZ whom it may concern:

Be it known that I, PARKER G. WEBBER, a citizen of the United States, residing at Stoneham, in the county of Middlesex, State of Massachusetts, have invented certain new and useful Improvements in Ventilators for Storm- Windows; and I do hereby declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others skilled in the art towhich it appertains to make and use the same. I

This invention relates to ventilators; and it has for its object to provide a cheap and simple ventilator which may be employed in connection with storm-windows without materially increasing thecost thereof and which while permitting of eflicient ventilation when desired will under normal conditions effectively prevent' admission of air.

Other-objects and advantages of the invention will be understood from the following de- 1 scription.

In the drawings forming a portion of this Specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is an elevation showing a window equipped with a ventilator embodying the present invention. Fig. 2 is a section taken,v

horizontally through the bottom rail of the sash. Fig. 3 is a perspective view showing the inner member of the ventilatorcasing.

Fig. 4 is a perspective view showing the outer member of the ventilator-casing. Fig. 5 is a view showing the blank of which the outer member .ofthe casing is formed.

' -Referring now to the drawings, there is shown a storm-window or sash, in the bottom rail 5 of which is arranged the present ventilator, it being understood, however, that the ventilator 'may be elsewhere placed in the sash. There is illustrated one embodiment of the invention of such construction as'to permit it to be made of sheet metal and at a very low cost.

The casing of the ventilator is formed of an inner member and an outer member, the former consisting of plate 6, of sheet metal, having a rectangular opening 9 in its central portion, the plate being slit on the lines 10 from the corners of the central opening in the diflange.

rection of the outer corners of the plate to form wings 12, 13, 14., and 15, which are bent of the plate, as illustrated.

From the outer corners of the plate 6 are cut angular pieces resulting in the correspondingly-shaped notches 14 and outerwings 15, 16, and 17, these notches 14: being formed at one end only of the plate. The upper and lower wings 15 and 17 are bent to lie over and spaced from the body of the plate 6, as is also the wing 16, the sides of the corner-notches forming ends of the wings abutting and being soldered together, there being formed a guideway 19 between the'wings and the body of the plate to receive a sliding closure 20, which is formed of a sheet of metal having one end reduced in'width and bent upon itself to form a handle 21, which may be grasped to adjust the slide, so that it may close a greater or lesser part of the central opening through the plate 6. V

The outer member of the casing consists of a strip of metal one edge portion of which is bent to lie at right angles to the body of the plate in the form of a flange 22, which is slit at intervals to permit the plate to be bent upon itself into rectangular form in the shape of a boxing, including the top and bottom 23 and 24 and the ends 25 and 26, from one edge of each of which projects a portion of the said The boxing is disposed in acorresponding opening 27 in the bottom rail of the sash, with the flange 22 against the outer face of the rail, brads or screws 29 being passed through the flange or-wings formed by dividing the flange into sections and into the sash. The plate 6 is then adjusted to lie against the inner face of the bottom rail 5, with the wings- The'sliding closure is thenv engaged in'the.

guideway in the plate 6, in which it may be slid to expose the entire opening through the rail or a part of it, as preferred.

It will be understood that the construction 6 above described can be made at very little expense, so that it will not materially increase TOO the cost of the storm-Window or sash and that l therein, a plate slidably engaged in the guides modifications may be made and any suitable and movable therein to close the opening to 5 materials and proportions used for the diiferdifferent degrees, and means engaged through ent parts Without departing from the spirit of the overlapped portions of the members and 5 the invention. in the sash for holding said members to the What is claimed is sash.
